Rowan, 34, is charged with one count of aggravated battery and one count of aggravated battery against a household member.

Rosenblum, 27, is charged with aiding and abetting a felon.

The charges stem from a call to Los Alamos police dispatch at 11:30 p.m. Friday reporting a fight in progress and that someone had been stabbed.

LAPD Cpl. Adam Jung arrived at 939 Iris St., and was advised by witnesses that Ian Cornelius, 24, had been stabbed multiple times.

Cornelius told police officers at the scene that Rowan had stabbed him, according to the arrest warrant affidavit.

A second victim, Britney Gutierrez, 27, also told police that Rowan stabbed Cornelius, according to court documents. She said that Rowan was her ex-boyfriend and that he also stabbed her, causing a gash across three knuckles of her hand.
